Abstract

PURPOSE:To obtain a synthesized copy of high image density only though one time of elctric charging by using a composite photoreceptor combined with a photoconductive layer exhibiting sensitivity to A color light and having no sensitivity to B color light and a photoconductive layer exhibiting sensitivities reverse from these. CONSTITUTION:The 1st photoconductive layer 2 having sensitivity to A color light and having no sensitivity to B color light and the 2nd photoconductive layer 3 having sensitivity to the B color light and having no sensitivity to the A color light are successively laminated on a conductive substrate 1, whereby a composite photoreceptor 4 is formed. The receptor 4 is charged to a prescribed polarity in the dark to expose the B color light under an original I having an information image alpha, thence it is exposed with the A color light under an original II having an information image beta, whereby the electrostatic latent images alpha', beta' of the same polarity corresponding to the images alpha, beta are formed respectively on the surface of the photoreceptor 4. Thence, they are developed simultaneously by the toner 5 of the reversed polarity from that of the latent images alpha', beta' and are fixed, whereby the intended synthesized copy is obtained.
